Taro (Yuichi Saito, 10?) discovers his mother bathing with an unknown little girl, Emi (Catharia, 10?), and is surprised by the situation. The reason is also beacause Emi doesn't look like a Japanese girl (she is the daughter of an American man and a Japanese woman, the film is set during WW2).

Taro and Emi play in a river wearing only their underwear. Suddenly both Taro and Emi find themselves with their underwear down (for Taro we can clearly see that the cause is due to the current of the river, for Emi we can think the same thing happened, because it is not shown). Taro, realizing his nakedness immediately covers himself with his hands, Emi doesn't (brief full frontal in distance of both), after an embarrassing silence the two say something to each other and after putting their underwear back on, they start playing again.

Taro and Emi sleep hand in hand near the river.

Taro and Emi play on the beach.

Continuation of the previous scene with Taro and Emi playing on the beach.

The air raid alarm sounds but Taro and Emi ignore it.

Taro's sister and her boyfriend (?) take Taro and Emi away.

Tairo and Emi are inside a hut to take shelter from enemy planes. Emi seems upset by what the Taro's sister's boyfriend (?) tells her and runs away with her gaze turned towards the sky, the word "papa" is clearly heard. Immediately after the plane shoots towards Emi and the others who ran after her.

Emi's lifeless body lies on the beach while Taro whispers her name.
